People getting defensive at car shows!

Man, the only new car around me that participates in shows for trophy's is a highly modified 2019 mustang with around 1000 horsepower. we all like the guy though because he did all the work on it and learned how to tune it with his laptop by himself.
as long as you are a good person and not an ***, I say you are welcome to compete in shows.
He would have my respect. There's a major difference in being an actual hot rodder and just writing a check.
